74LVT162240MEAX

Overview

The onsemi 74LVT162240MEAX is a low-voltage 16-bit inverting buffer and line driver featuring 3-STATE outputs with integrated 25Ω series resistors. It operates within a supply voltage range of 2.7V to 3.6V, supporting TTL interface capability to 5V environments. The device utilizes advanced BiCMOS technology for high-speed operation while maintaining low power dissipation. Key electrical parameters include propagation delays ranging from 1.0ns to 4.8ns depending on conditions, output currents of -12mA (HIGH) and 12mA (LOW), and an operating temperature range of -40°C to +85°C. It is housed in a 48-lead SSOP package.

Feature Summary

• Integrated 25Ω series resistance in both HIGH and LOW output states reduces line noise and eliminates the need for external termination resistors.
• Nibble-controlled architecture allows independent control of four 4-bit sections or combined 16-bit operation via shorted Output Enable inputs.
• Power Up/Down high impedance state ensures glitch-free bus loading during power transitions.
• Live insertion and extraction are permitted without causing system interference.

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitter/receiver circuits

Procurement Notes

Verify component authenticity through authorized distribution channels as counterfeits exist. Confirm package marking matches MS48A SSOP specifications. Check datasheet revisions for potential parameter updates. Ensure ESD handling protocols are followed due to CMOS sensitivity. Validate supply voltage compatibility before integration into 3.3V systems.

Selection Notes

Select this component when designing 3.3V logic interfaces requiring 16-bit data transmission with controlled signal integrity. The built-in series resistance simplifies PCB layout by removing external termination requirements. Consider the LVTH variant if bushold input functionality is required to eliminate external pull-up resistors for unused inputs.

Part Context

This device belongs to the LVT logic family, designed for low-voltage applications. It is functionally compatible with the standard 74 series 162240 but optimized for 3.3V operation. The MEAX suffix indicates the SSOP package with tape and reel packaging options available.

Replacement Considerations

The 74LVTH162240MEA serves as a functional substitute, offering identical electrical characteristics with the addition of bushold inputs. Verify pinout compatibility and ensure the application does not strictly require the non-bushold configuration of the base model.
